POC Clutches
For mounting dimensions, see pages 12-13 of
this service manual.
Step 1: Bolt Clutch in Place
Mount the clutch to a vertical surface, using
customer supplied fasteners. For models larger
than size 5, the housing must be secured on
both input and output sides. See Figure 1. A flat
horizontal mounting surface is required for foot
mounted size 80 clutches. See Figure 2.
Step 2: Make Mechanical Connections
Mount couplings, pulleys, or sprockets to the
male shafts per the manufacturers' recommen-
dations. The pulleys, sprockets, and couplings
are customer supplied.
PHC-R Clutches
For mounting dimensions, please refer to page
11 of this service manual.
Step 1: Secure Clutch to Shaft
Slide the clutch on the shaft that is being driven
by the clutch. Secure the clutch with customer
supplied locking collars or other suitable means.
(Mounting the clutch on the shaft that is driving
the clutch is acceptable, but doing so increases
total load inertia.)
Step 2: Attach Antirotation Restraint
Since this is a shaft mounted unit with a station-
ary field supported by bearings, the field must
be restrained to prevent bearing drag from
pulling on the lead wires. Restraining device
must not preload the bearing.
The field can be restrained with a holding arm
attached to the tapped holes in the field housing
or with capscrews through a mounting bracket
as shown in Figure 3. If bolts are used, first
hand tighten the bolt just enough to take out the
clearance under the head of the capscrew. Then
tighten the locking nut while preventing the bolt
from turning.
